Report describing the results of an interdisciplinary environmental study of the World Trade Center (WTC) area after the attack on September 11, 2001. The investigations included imaging spectroscopy mapping and laboratory analysis.

We put seismic monitoring instruments into 20 VA hospital buildings, connected with computers that analyze their data to determine rapidly the structural health of the buildings in the event of earthquakes.

Using a geographic dataset of structures, with more than 5500 structures that were destroyed or damaged by wildfire since 2001, we identified the main contributors to property loss in two extensive, fire-prone regions in southern California.

Specialized monitoring systems installed in a VA hospital in Memphis, TN will help us to design safer hospitals and other buildings and to prevent loss of life in this and similar earthquake-prone areas.

USGS operates a low-enriched uranium-fueled, pool-type reactor located at the Denver Federal Center. We use it for analyses of fissile and fissionable isotopes, geochemical analysis, and geochronology.

Iron ore containing elevated concentrations of trace metals was smelted here during 113 years of operation (1771-1883). We sampled a variety of materials nearby to determine the amount of metals such as arsenic, chromium, copper, lead, and zinc.
